Be -i't known that WILLIAM GRABEN- ing at Flasher, inxtlie county of7M0-rton,

Stateof North' Dakota, have invented cerfoot cross legs tain new and useful inproveinents` in 15 and 16 -pivot'ally connectedtogether at AlarmjCots, and' I do hereby declare the their centers as at 17.` Tliese foot cross legs pertainsjto make and use the same. s head This inventionrelates to cots' and parcommonly known as alarmlegs 10 ingsto receive vrespectively the A'extension pinsll and 19. e side member 20 is p .tivelylocked upon'the upper -end of c'rosslegsr10-andl5 'strap irons 21-which'embracerespective ends f of e side :memberand have-th provision of alco't of the typereferred respective cross legs'f l0 and' 15 by to wlr'ch will be simple in c0nstructi`on, said arms and adaptehfto be folded in a compact manner. l for transportation andwhich will efficiently. serve the prposes for which it is intended.

lith the allieve and oth and 15 'respectively is e side member` cots. .s p The object ofthe invention resides in the 'upper ends of the cross legs l1 andl is a side member 23 which" .i's'also'provided with openings 24 .to receive the pinextensions 14 the invention consists in the details of con- 0I 1 the' Upper end 0f the CIOSS legs 11 :md 16 struction and in the arrangement'and comrespect-Wely- T1118 Slde member 93 is' also' ination of parte' to. be hereinafter more pnsitively'locked upon the upper ends ofthe fully described and particularly pointed out CI'OSS ,legs ll'and 1 6' by means 0f Strap IOHS in the appended Claim, secured to the legs 11 andl respect-ivel In describing the invention in detail, re"- the accompanying drawings wherein like charactersy of refer- 0 all@ 154 'enceidenote corresponding parts inthe sev.` The head end of the side member 20.` has era] views, and in which` 1 nted on its outer face a clip 26 while a similar clip 27 is correspondingly mounted on the head end of th necting the side members 20 `and 23' at their head-end is across barA which pair of hinged sections ,28 and ends ofl which l .and rotatably showing' the position ofthe ammock element thereof after actuation ofwth'e vtrip 3, a fragmental perspecghead ndj of the cot; Fig; f1, a-fragmental'perspective view of the foot end of the cot, FigI 5. a section onitlieline` 5--5 ovFig. 4. and'Fig. 6, a view showing he sect-ions' 28 end'29 are provided with av plurality of vertically directed pins or studs 30 for a purpose that will presently appear.

The side member 23 is provided at its oot end on its inner face with an angular by the movement of an object across a predetermined point in a ive way or the like.

ferring to' the drawings, Athe cot is .shown as comprising head cross legs 10 andich-is providedateachend with openthey'ineans of vU-shaped cross legs. ASiipported upper. ends oftheheadand` foot cross.

eir arms serespectively. `Supported upon thev` i comprises a Yioo construct-ion it will be apparent that the ing effected vafter the manner of disengagcally and opens through the upper side of p said member while the other arm of said slot is disposed horizontally. Formed in the side member 2O at its foot end in trans; verse alinelnent with the 'outer end of the horizontal arm of the slot 3l is a bearing' opening 32. Rotatably mounted in the opening 32 and in the horizontal arm of the slot 31 are the trunnions of a drum 33. By this drum can be readily removed from its bearingsin the side members 20 and 23\by reason of the angular slot 31 said removal be;

ing ay bayonet joint.

Mounted centrally of the drum 33A is a radially disposed arm The drum 33 is further provided'with a plurality of radial pins 37 for a purpose that will presently appear. l

The hammock element of the cot coinprises a suitable flexible fabric 3S having mounted on its upper or head end a pillow section 39. Also mounted on the head Vend of the hammock; element is a plurality of rings 4-0 adapted for detachable engagement with respectivel pins 30 to secure the head end of the fabric upon the cot frame. The foot end of the fabric 38 has secured thereto a plurality of flexible connections 41, the free ends of'which are secured respectively to the pins 37 on the drum By this con struction it will be apparent that as the drum 233 is rotated in one direction the fabrie 38 'will be drawn taut, while the reverse rotation offsaid drum will cause'the. fabric to become slack and assume a concave shape.

In order to set the cot for use it is placed adjacent a suitable drive way or passage such as are present in a livery stable. The drum 33 is then rotated so as to bring" .the fabric. to a taut condition and disposed sul stantially horizontal. When this condition of the, fabric 38 is presentI the arm 35 is disposed vertically and the loop end 4:2 of a trip rod 43 is engaged with the outer end of said arm. rThis trip arm 43 is in turn sev cured to a suitable connection it which latter extends across the drive way and is suit,- ably anchored to an adjacent fixed part.

Then the connection Leis thus disposed it will secure the drum 33 against rotation as will be apparent andthe fabric 38 will then support the body of thev occupant in. the proper 'manner .for sleeping. However, when a teanr passes along the drive way same will engage .the connection 4i and as the fabric 38 and connections Lll possessl a certain degree of elasticity, the drum 33 and' arm 35 will be rotated so that said. arm will move outwardly of the cot. This movement will at a predetermined time effect the disengagement of the trip rod 43 from the arm 35 as will be obvious. The weight of the body of 'the occupant will then unwind the connections 4l from the drum 33 .and cause the fabric 38 to fall sharply to the position shown in Fig. 2 and thus awaken the 'occupant. It will be further noted that as the various parts of the cotare detachable one -from the other it` will permit. same to be folded compactly so as to enable the easy and ready transportation thereof.

The. fabric 38 is provided wit-h a lateral flap 38 which isadapted to be returned v upon the fabric so as to cover`- the oo citpant and afford the necessary warmth.

lVhat' 1s claimed 1s In a cot, the combination of a frame, a hammock, means for detach'abi'y securing one end of the hammock tp the frame, la

drum rotatably mounted in. said frame, conneet-ions between the other end of the hammock and the vdrum whereby the rotation of the lattcrn-one direction will draw the hammock taut,- a radial arm carried by the drum, a flexible connectionsecured to a fixed part, and a trip rod secured to said flexible connection and detachably 'engaging said radial arm to lock the drum against rotation. said trip rod being,` releasable from engagement with the radial arm b v'a lateral pressure againstsaid flexible connection whereby the weight of the occupant will rotate the drum to unwind the connections between the hammock and said drum from the latter.

ln testimony whereof. l atiix my sfgilature7 in presence of two witnesses.
